2012年10月31日下午四点,我接到了义乌市四星级教师评比的课题——《数据的收集与整理》。书上设计的情景不符合义乌学生,而且两个实例没有关联,为了让数学更贴近生活,我对教材进行了改编。我想到义乌市将要举行2012年中小学篮球赛,以篮球赛为载体来设计这节课更贴近学生生活。于是我按照这个思路精心设计了这堂课。这样设计一方面是让学生体会数学来源于生活,又反作用于生活,另一方面使整节课的知识点用一条线串起来。课堂上,宾王中学的学生非常活跃,整节课 At four o’clock on the afternoon of October 31, 2012, I received the topic of “four-star teacher evaluation in Yiwu City - Collection and Sorting of Data.” The book design scenarios do not meet Yiwu students, and two examples are not related, in order to make mathematics closer to life, I adapted the textbook. I think Yiwu City, 2012 will be held in primary and secondary basketball games to basketball as a carrier to design this lesson closer to student life. So I carefully designed this lesson according to this idea. This design on the one hand is to allow students to experience mathematics from life, but also on the role of life, on the other hand, the knowledge of the whole class points with a line string together. Classroom, Binwang high school students are very active, the whole class
